I am using grpc-web to communicate with a java backend over gRPC. I am using ReactJS on the frontend which uses grpc-web to interpret the protobuffers.
I am getting this strange error. My protos are correct ( I checked using a reflection tool called "bloom" so the backend is just fine) This somehow seems like an error internal to the grpc libraries I am using in ReactJS.
I get the following error:
TypeError: Cannot read properties of undefined (reading 'MethodInfo')
The above error points to my proto file: dashboard_services_grpc_web_pb.js
In this file, it point to this line
const methodInfo_DashboardService_userLogin = new grpc.web.AbstractClientBase.MethodInfo( ...... );
I have a hard time solving this because according to my understanding, grpc.web.AbstractClientBase is something native to grpc-web.
I have also reinstalled my node_modules in hopes that this is a version issue but no avail.
I had the same issue because I was using an old release of the executable protoc-gen-grpc-web with respect to the current version of grpc-web. Using version 1.3.0 for both solved the issue for me.
You can download the latest release of protoc-gen-grpc-web here.
